Angled truck bed light holder

I bought some lights to put in the bed of my truck so I could see when I am unloading at night. The only problem was that the lights attached to the bed parallel this would not allow me to hide them under the rail
while providing sufficient light. These holders are angled down to allow for the lights to be hidden. You can see the huge difference these
lights make in the picture and they are hidden when not in use.
